Drum material-fetching machine moving avertence detection device and working method thereof

Abstract

The invention discloses a line feed deflexion detecting device of a roller reclaimer, comprising a connecting rod amplifying system, a rotational shaft device, a speed increaser, an encoder and a protecting device, wherein connecting rod reamed points of the connecting rod amplifying system are maintenance-free self-lubricating joint bearings, and the rotational device adopts a rolling bearing and a sealing structure. When the roller relcaimer generates line feed deflexion, a bridge frame and a door leg generate miniature rotor angle around the central line M, and the rotor angle is further amplified by the connecting rod amplifying system, the rotational shaft device and the speed increaser and is transmitted to the encoder which transmits the deflexion rotor angle to a control system of the roller relaimer, the deflexion correction is performed by the control system of the roller reclaimer, and the protecting device realizes the protection function in the failure state. The device can remove the jammed phenomenon of the line feed deflexion detecting device caused by the structural error, realizes the flexible rotation of the rotational shaft, accurate detection and the automatic control, and does not have maintenance workload.

Description

technical field [0001] The invention relates to an industrial detection device and a working method thereof, in particular to a travel deflection detection device of a drum reclaimer and a working method thereof. Background technique [0002] The travel on both sides of the drum reclaimer is driven by different driving devices. If the travel is not synchronized, the equipment will be skewed, which is extremely unfavorable to the reclaiming operation. Therefore, people have designed a deflection detection device for the drum reclaimer. The current travel deflection detection device of the drum reclaimer is a stay rope position detection system, which is composed of a shift fork connection system, a fixed shaft, a protection device, a pulley and a stay rope position detection switch. But this system has the following problems: [0003] 1. In order to compensate for the jamming of the detection system caused by the structural error of the equipment, there is a certain gap when...

AI Technical Summary

Problems solved by technology

[0003] 1. In order to compensate for the structural error of the equipment and cause the detection system to be stuck, there is a certain gap when the fork head of the fork connection system is connected to the round steel, resulting in a certain lag and error in the detection value of the pull rope position detection switch

[0004] 2. Since at least two reversing pulleys and one steel wire are required for detection, the reliability of the detection device is poor, the accuracy is also low, and the workload of maintenance and repair is large

[0005] 3. Not suitable for automatic operation requirements
